You need to do the above as root:

aklaver(at)arkansas:~$ pg_lsclusters
Ver Cluster Port Status Owner Data directory Log file
11 main 5431 down postgres /var/lib/postgresql/11/main
/var/log/postgresql/postgresql-11-main.log
12 main 5432 online postgres /var/lib/postgresql/12/main
/var/log/postgresql/postgresql-12-main.log

aklaver(at)arkansas:~$ pg_ctlcluster 11 main start
Warning: the cluster will not be running as a systemd service. Consider
using systemctl:
sudo systemctl start postgresql(at)11-main
Error: You must run this program as the cluster owner (postgres) or root

aklaver(at)arkansas:~$ sudo pg_ctlcluster 11 main start
[sudo] password for aklaver:

aklaver(at)arkansas:~$ pg_lsclusters
Ver Cluster Port Status Owner Data directory Log file
11 main 5431 online postgres /var/lib/postgresql/11/main
/var/log/postgresql/postgresql-11-main.log
12 main 5432 online postgres /var/lib/postgresql/12/main
/var/log/postgresql/postgresql-12-main.log

Also the cluster is already running.
To confirm what you have running do:

ps ax | grep post
